GXP 1625 problem


Hi, I have a problem with the GXP1625

when you pick up the handset, the call lasts a few seconds to listen, even if you want to make a call with the loudspeaker.
If I want to pick up a call with the keys * 8 # it takes several seconds to activate the headset or speaker, my VoIP system is running on Asterisk and soon we will migrate to Issable PBX


firmware on 1625, is it onsite or hosted PBX
